    Summary

    Luke spoke to Percy. He set the scorpion on him. He teleported away. But now he's back in the training arena, asking Percy to come into the woods with him. And no matter how many times he kills him, time just starts again.

    Or: Just before he's destroyed, Kronos uses the last of his power to try to fix what he thinks went wrong. Luke Castellan will recruit Percy Jackson to the Titans' side and avert total disaster. Or he'll never escape the loop.

    Summary

    Shortly after defeating Gaea with the Seven in the second Gigantomachy, Percy finds himself thrown through a fountain into a time where Gaea is once again stirring, the gods are elitist (moreso than usual, anyway), and the first Gigantomachy is right around the corner.

    It's... super. Really appreciate this one, gramps. Keep rotting in the Pit.

    Summary

    Percy might be battling a mild case of amnesia, but he's pretty sure this isn't what he signed up for. Also, he missed the day in school where they learned about respecting the spacetime continuum.

    or, Percy is reborn at the founding of Athens and immediately wrecks the place.

    Summary

    The rivalry began long before Percy Jackson and Jason Grace met. It began with one arriving at the other's Camp, with one filling the other's shoes. A rivalry does not need attention to grow. It will feed, and fester, and bloat until it is confronted and either defeated or fulfilled.

    Percy's problem isn't with Jason. It's with the Romans' way of things. It's with their child army, and their blind compliance to the gods, and their harsh standards and the division between their cohorts. Praetor Jason Grace is just the easiest target.

    Jason doesn't have an issue with Percy. He just has an issue with how much acknowledgement the gods give the Greeks, with how low the Greeks' lifespan is, with how much freer and happier the Greeks are. He has an issue with the fact that his father still won't acknowledge him, won't talk to him. He has an issue with the sense of wrongness the idea of being Greek or Roman gives him. Maybe Percy is just the easiest scapegoat, but...Jason has no other target.
